数据发掘功能在生产管理软件(MES软件)排产体系中的效果-->

树立PMC排 程排产体系的意图是进步管理水平。数据发掘的意图是从很多数据中寻觅有用的信息。它可经过切片旋转、钻取等方法,对同一层面的数据从不一样的视点进行剖析, 即变换剖析疑问的视点及对数据的细节从不一样的层次进行调查,从而为决议计划供给根据,具体地说,即是为用户供给一种决议计划撑持东西,使用户在决议计划剖析的进程中把 注意力会集在剖析数据上。
  数据发掘即是从很多的、不完全的、有噪声的、含糊的和随机的数据中,获取隐含在其间的、大家事前不知道的、但又是潜在有用的信息和常识的进程,并运用 这些信息协助、影响决议计划。它不仅是面向特定数据库的简略检索查询调用,并且要对这些数据进行微观、中观乃至微观的计算、剖析、归纳和推理,以辅导实际疑问 的处理,并妄图发现各要素之间的相互关系,乃至使用已有的数据对将来的活动进行猜测。
  数据发掘与传统的数据剖析比较,它能经过数据发掘东西变换审视疑问的视点,发掘躲藏的信息,发现被疏忽的要素。因而,数据发掘所得到的信息应具有事前不知道、有用和有用三大特征。
